BACKGROUND

Many users of mobile devices are becoming increasingly dependent ontheir capabilities to provide information in real-time, as the user ismoving through his/her daily activities. For example, the user may callother people, send and receive text messages, send and receive email,and engage in instant messaging interactions with others. As the usersare making decisions throughout the day, they frequently prefer toobtain opinions from others, to provide some basis for consideration oftheir ultimate decisions. For example, if a user is debating whether toeat lunch at a restaurant that is located a few feet from where they arecurrently standing, he/she may wish that opinions from his/her friendswere available with regard to the quality of food at the restaurant.

Similar questions may arise, for example, in the context of selectingmovies or shows to watch, deciding what clothing to purchase, decidingwhat music to purchase for player devices. Other examples may includedecisions regarding how to navigate to various geographic locations froma current location (based on opinions of friends), decisions regardingpersonal relationships (e.g., whether a marriage proposal is in order,whether to ask someone for a date), and decisions regarding personalopinions (e.g., who is liked/disliked by others, and why, who is bestcandidate in election campaign). For many scenarios, the user may desirean opinion in real-time, as he/she may only have a few minutes/secondsto ponder a decision (e.g., how to navigate, where to eat a meal, whichmovie to watch at a cinema). Making calls to friends and sendingemails/messages may consume more time than the user has available formaking the decision. Further, querying a search engine may provideopinion information regarding various entities, but the opinions may bethose of people who are unknown personally to the user.

DETAILED DESCRIPTION

Many users of computing devices depend on the devices to aid in theusers' decision-making activities. As computing technology has advanced,so has the capability of many devices to provide large amounts ofinformation in real-time, in a mobile environment.

Many users are also members of one or more social networking services,building their circles of friend connections on a daily basis. In suchsocial networking environments, it is possible to restrict access tovarious elements of personal member information to the member andhis/her friends in the system. For example, the social networkingservice may track the “friend” relationships (agreed to by the members)via a social graph structure. For example, a social graph may includenodes representing individual members of the service, with edgesconnecting the nodes representing relationships such as a “friend”relationship (e.g., node X may be connected to node Y via a “friend”edge, indicating that member X is a “friend” of member Y). Such a graphmay be used by the system in deciding when access to certain informationto members may be/not be permitted. Access to the “friend” informationfor individual members may be authorized when an individual member logsin to his/her user account in the system.

If a user of a mobile device wishes to obtain an opinion from one ormore of their “friends”, the user may not have time to select a list ofthe people they think would provide the most trusted informationregarding various activities. For example, if the user is debatingwhether to eat lunch at a restaurant that is located a few feet fromwhere they are currently standing, he/she may not have several minutesto key in a question on a mobile device, and then generate a list ofintended recipients that may have the most relevant opinions with regardto that nearby restaurant. For example, if the user is currentlystanding in downtown Seattle, he/she may not want to send a request foran opinion on a Seattle-based local restaurant to an Australian “friend”residing in Perth, Australia. Thus, the user may wish to quickly obtaina list of his/her “friends” who might be able to provide trustworthyopinions on the restaurant (and not “friends” who might be bothered bymessages that may seem irrelevant to them personally).

Example techniques discussed herein may provide simple user experiencesfor large-scale mobile social interaction. For example, a user mayeasily ask a binary question to his/her friends and obtain a response,for example, based on votes provided by the friends. For example, a usermay obtain a response, from his/her “friends”, to a question regardingwhether they should see a particular movie, the response arriving in atime frame of a few minutes, or seconds.

Example techniques discussed herein may provide techniques for users toeasily and quickly ask and answer questions. According to an exampleembodiment, questions may be suggested to the user as he/she enters aquestion. For example, the suggested questions may be based on theuser's demographic and prior interests/questions, to predict potentialfuture questions and minimize keystrokes for generating a questionquickly.

According to an example embodiment, binary questions may request binaryresponses, which may provide the responder with a simple button toselect for responding (e.g., the responder may not need to type any textto respond—simply select a binary response, via one keystroke orone-word verbal command). For example, the binary responses maygeneralize to not only meaning “yes/no”, but may also indicate “beenthere/not”, “ate that/not”, or “seen that/not”.

According to an example embodiment, push notifications for variousquestions from a user may be sent to “closer” friends of the user, or tofriends who may be more likely to answer particular questions, based onan analysis of information associated with “friends” of the user. Forexample, a “friend” residing in Australia may not be selected as arecipient for question from a Seattle resident regarding a local Seattlerestaurant (unless that “friend” is associated with a history ofactivities or interests in the Seattle area).

According to an example embodiment, data obtained from histories ofquestions/answers in a question processing system may be mined andinformation may be inferred, based on the questions/answers (e.g., userdemographic, shopping behavior, past experiences, expertise, interests,influencers). For example, if a user asks several questions regardingartists such as Justin Bieber, as well as questions regarding femaleteen-level clothing, then an inference may be drawn (with regard to theuser demographic) that the user may be a teen-aged female.

According to an example embodiment, a search icon may be presented witheach question that allows users viewing the questions to take actions.According to an example embodiment, an analysis of an intent of aquestion may be used by the system to determine what actions a user maybe likely to take. For example, if a user is viewing a questionregarding a named restaurant, then a search icon may provide quickaccess to information regarding the restaurant location, theowner/proprietor, the menu, and ratings posted online or in otherinformation sources. For example, the system may receive a questionregarding the restaurant, and may determine an intent of the question asa query on the location, the quality of food, or the overall cost ofmeals. The determination may be based, for example, on a history ofquestions and other information associated with the restaurant, theowner/proprietor, the location of the restaurant, the type of foodassociated with the restaurant, and/or attributes associated with theasking user and/or “friends” of the asking user. The determination maybe based, for example, on searches of the web and other informationalsources.

As further discussed herein, FIG. 1 is a block diagram of a system 100for processing user questions. As shown in FIG. 1, a system 100 mayinclude a question processing manager 102. According to an exampleembodiment, the question processing manager 102 may be embodied viaexecutable instructions stored on a computer-readable storage medium.For example, the executable instructions may, when executed, cause oneor more data processing apparatuses to perform steps that may beassociated with example techniques as discussed further herein.

As shown in FIG. 1, the question processing manager 102 may include aquestion input engine 104 that may be configured to receive a question106 from a first user 108.

According to an example embodiment, the question processing manager 102may include a service memory 110 that may store the question 106. Inthis context, a “memory” may include a single memory device or multiplememory devices configured to store data and/or instructions. Further,the service memory 110 may span multiple distributed storage devices.

According to an example embodiment, a service user interface engine 112may manage communications between the user 108 and the questionprocessing manager 102. The user 108 may be associated with a receivingdevice 114 that may be associated with a display 116 and otherinput/output devices. For example, the display 116 may be configured tocommunicate with the receiving device 114, via internal device buscommunications, or via at least one network connection.

According to an example embodiment, the question processing manager 102may include a service network communication engine 118 that may managenetwork communication between the question processing manager 102 andother entities that may communicate with the question processing manager102 via at least one network 120. For example, the network 120 mayinclude one or more networks such as the Internet, at least one wirelessnetwork, or at least one wired network. For example, the network 120 mayinclude a cellular network, a radio network, or any type of network thatmay support transmission of data for the question processing manager102. For example, the service network communication engine 118 maymanage network communications between the question processing manager102 and the receiving device 114. For example, the service networkcommunication engine 118 may manage network communication between theservice user interface engine 112 and the receiving device 114.

A connection determination engine 122 may be configured to determine,via a device processor 124, a first group 126 of connection users havinga connection user association with the first user 108 in a content graph128.

In this context, a “processor” may include a single processor ormultiple processors configured to process instructions associated with aprocessing system. A processor may thus include multiple processorsprocessing instructions in parallel and/or in a distributed manner.Although the device processor 124 is depicted as external to thequestion processing manager 102 in FIG. 1, one skilled in the art ofdata processing will appreciate that the device processor 124 may beimplemented as a single component, and/or as distributed units which maybe located internally or externally to the question processing manager102, and/or any of its elements.

One skilled in the art of data processing may understand that a “graph”generally may refer to a structure that includes nodes and edges. Thenodes may represent entities, and each edge may connect a pair of nodes,the edge representing a relationship between the connected pair ofnodes.

In this context, a “content graph” may thus refer to a graph structurethat may include nodes representing entities (e.g., persons, questions,attributes) and edges connecting pairs of nodes, the edges representingrelationships between respective connected pairs of nodes. For example,a content graph question node may represent a question, a user node mayrepresent a user of a system, and an edge connecting the question nodeand the user node may represent an action indicating the user asking thequestion. Further a second user node may be connected to the questionnode via an edge that represents an action indicating the user providingan answer to the question. According to an example embodiment,cumulative results for the question may be stored in association withthe question node, and/or individual answers may be stored inassociation with user nodes associated with respective responders to thequestion. According to an example embodiment, an edge may connect theuser node and the second node indicating a “friend” relationship betweenthe connected nodes (and the respective users).

According to an example embodiment, a type of connection may be storedwith the edges. For example, if a connection for a particular graph isdetermined via information from an external source (e.g., a socialnetwork source), then information identifying the source of theconnection identification may be stored in association with the edgeindicating the connection. For example, if a user identifies a “friend”then an edge connecting the user node with a node representing thefriend may indicate that the user provided the indication of the“friend” relationship.

According to an example embodiment, an answer to a question may also bestored in association with an edge connecting the question node to thenode associated with the answering party. According to an exampleembodiment, attributes associated with a connection may be stored inassociation with edges connecting nodes in the content graph 128.

According to an example embodiment, the content graph 128 may be storedin a content repository 130, which may be located internally orexternally to the question processing manager 102. According to anexample embodiment, a content repository interface engine 132 may managecommunications between the content repository 130 and other elements ofthe question processing manager 102.

A question dissemination engine 134 may be configured to initiate atransmission of the question 106 and a search link 136 to each of atleast a portion of the connection users included in the first group 126.

A response receiving engine 138 may be configured to receive one or morefirst responses 140 from one or more of the connection users included inthe at least a portion of the connection users.

A graph update engine 142 may be configured to initiate a first updateto the content graph 128, the first update including an addition of afirst node associated with the received question 106 and a first linkassociating the first user 108 with the first node, the first linkindicating an action of asking the question, and initiate a secondupdate to the content graph, the second update including an addition ofa second link associating one of the connection users associated withone of the received first responses 140, with the first node, the firstlink indicating an action of answering the question.

According to an example embodiment, a question content determinationengine 144 may be configured to determine a content 146 associated withthe question 106 and to determine the search link 136 based ondetermining web sites associated with information associated with thecontent 146 associated with the question 106. For example, the questioncontent determination engine 144 may determine the content 146associated with the question 106 and may infer an intent associated withthe question. For example, if a question relates to a restaurant ormovie, then an inference may be made that an intent of the question mayinvolve a query regarding whether the querying user should eat at therestaurant, or pay for tickets to watch the movie. Other example intentsthat may be inferred from such questions may include queries regardingthe quality/age-appropriateness of the food or movie, the location(e.g., navigational instructions), or the ambience of anestablishment/surrounding neighborhood.

For example, a task associated with a question “Have you been to SpaceNeedle?” might include obtaining navigational directions to the SpaceNeedle. Other actions may include “buy movie ticket”, “shop for shoes”,or “make dinner reservations”. The search link 136 may thus includeinformation relating to completing such inferred tasks. For example, atask indicated as “make dinner reservations” may include a link to anonline restaurant table reservation system, and may provide availabletimes to the first user 108 (or may provide a number to call, or mayoffer to auto-dial the number, if tables are indicated as unavailable).

For example, the search link 136 may include one-click access to apredetermined search of a search engine regarding keywords (or keywordsinferred by the question content determination engine 144) associatedwith the question. For example, the search link 136 may includeone-click access to information obtained by the question processingmanager 102 that the question content determination engine 144 maydetermine based on accessing the content graph 128, or a combination ofsearch engine results and information based on the content graph 128.

Thus, if a person viewing the question desires more information to aidin making his/her voting decision, or if the person viewing the questiondesires more information regarding possible intents of the question, thesearch link 136 may provide quick access to such information (e.g.,without keying in search terms).

According to an example embodiment, the connection determination engine122 may be configured to determine the first group 126 of connectionusers based on one or more friend connections associated with the firstuser 108 in a network or graph.

According to an example embodiment, a result determination engine 148may be configured to determine a first result 150 based on the receivedone or more first responses 140. According to an example embodiment, thegraph update engine 142 may be configured to initiate storage of thefirst result 150 in the first node.

According to an example embodiment, a result request engine 152 may beconfigured to receive a first result request 154 from the first user108. According to an example embodiment, the result determination engine148 may be configured to initiate a transmission of the first result 150to the first user 108, based on a traversal of the content graph 128.

According to an example embodiment, the result request engine 152 may beconfigured to receive the first result request 154 from one of theconnection users included in the first group 126. According to anexample embodiment, the result determination engine 152 may beconfigured to initiate a transmission of the first result 150 to the oneof the connection users included in the first group 126.

According to an example embodiment, the question 106 may include a queryassociated with a binary condition, and the one or more first responses140 may each include one of two binary response values.

According to an example embodiment, the question 106 may include a queryassociated with one of a yes/no condition or an up/down vote condition,According to an example embodiment, the one or more first responses 140may each include one of a yes/no value or an up/down vote value.

According to an example embodiment, the second update may include anaddition of a third node associated with the first response, a thirdlink associating the third node with the first node, the third linkindicating an answer relationship between the question and the firstresponse.

According to an example embodiment, a ranking determination engine 156may be configured to determine a ranking 158 of the connection usersincluded in the first group 126 based on comparing attributes associatedwith each of the connection users included in the first group 126 andattributes associated with content 146 of the question 106.

According to an example embodiment, a responder determination engine 160may be configured to determine the at least a portion of the first group126 of connection users based on the determined ranking 158.

According to an example embodiment, the ranking determination engine 156may be configured to determine the ranking 158 based on one or more oflocation information associated with the connection users, a connectionuser preference associated with the first user, location informationassociated with the first user 108, history information associated withthe connection users, or history information associated with the firstuser 108.

According to an example embodiment, an intent receiving engine 162 maybe configured to receive an indication 164 from the first user 108 of anintent to generate a user question. For example, the user 108 mayrequest a browser display of a user interface for receiving userquestions (e.g., by activating an application that is configured toreceive the user questions). The intent receiving engine 162 may thusreceive an indication that the first user 108 is requesting a display orinteractive application for providing his/her question.

According to an example embodiment, a suggestion determination engine166 may be configured to determine one or more user suggestion questions168 based on accessing a first user node in the content graph, the firstuser node associated with the first user 108, based on one or more of ahistory of questions associated with the first user 108, one or moreattributes associated with the first user 108, or a partial queryreceived from the first user 108. For example, the suggestiondetermination engine 166 may determine that the first user 108 isassociated with a history of asking his/her friends their opinionsregarding current movies, and may further determine a current locationassociated with the first user 108 based on location information thatmay be provided with a notification of an activation of a user deviceapplication associated with the question processing manager 102. Forexample, the suggestion determination engine 166 may infer questions,based on the history, a current time/date, and current location of thefirst user 108, that the first user 108 is likely to ask for opinionsregarding a movie currently running at a cinema near a current locationof the first user 108.

For example, the current location of the first user 108 may be obtainedfrom the first user 108 or from a device associated with the first user108. For example, computing devices associated with users may includeGlobal Positioning System (GPS) functionality that may providegeographic coordinates for determining locations. As another example,the first user 108 may provide location information, or locationinformation may be determined based on a port address on a network. Thelocation information may also be determined from an analysis of wirelessstation locations if the computing device associated with the first user108 is utilizing wireless communications.

According to an example embodiment, a suggestion output engine 170 maybe configured to initiate a transmission of the one or more usersuggestion questions 168 to a device associated with the first user 108.For example, based on a history of types of movies (e.g., drama, comedy,action thriller, romantic, teen theme, particular actor/actress star) inwhich the first user 108 may have indicated interests (e.g., viaquestions asked/answered by the first user 108 in the past), thesuggestion determination engine 166 may determine particular moviescurrently showing at a cinema nearby for inclusion in the suggestionquestions 168, including those scheduled to start in the next fewminutes after the transmission of the question 106. Thus, the first user108 may change his/her initial intended question from “Should I seemovie X” to “Should I see movie Y”, based on information provided by thesuggestion questions 168 to the first user 108. As another example, thesuggestion questions 168 may include suggestions of activities that mayappear more desirable to the first user 108 than his/her original plan.The first user 108 may thus select his/her preferred question from theuser suggestion questions 168 and receive swift feedback from his/her“friends”.

According to an example embodiment, the graph update engine 142 may beconfigured to initiate a third update to the content graph 128, thethird update including an update to a first user node in the contentgraph 128, the first user node associated with the first user, theupdate including updating one or more of demographic informationassociated with the first user 108, location information associated withthe first user 108, preference information associated with the firstuser 108, or behavior information associated with the first user 108.

According to an example embodiment, a group of connection users havingfriend connections to the user 108 may be determined based on accessinga social network 172. For example, the user 108 may log in to a serviceassociated with the system 100 by logging in to the social network 172(e.g., a posting social network, an instant messaging system).

According to an example embodiment, a network import manager 174 may beconfigured to access systems (e.g., the social network 172) to determinecontent and/or connections associated with users having nodes in thecontent graph 128 (e.g., the user 108), and to update the content graph128 based on information determined via the access. For example, if theuser 108 activates an application related to the question processingmanager 102, such that access to the social network 172 is enabled(e.g., via a login by the user 108), the network import manager 174 mayaccess the information that may be available to the user 108 via thesocial network 172 to update the content graph 128 over time. Forexample, the network import manager 174 may determine updates to theinformation in the social network 172 that has been updated byactivities related to the user 108, or to other social network usersconnected to the user 108 in the social network 172.

For example, the network import manager 174 may determine both socialconnections and content indicated in the social network 172, and mayupdate the content graph 128 to indicate either/both the socialconnections and/or the content associated with the social network 172that may be accessible via access permissions associated with the user108. For example, if the user 108 is connected to a “friend” in thesocial network 172, but the “friend” is not currently included in thecontent graph 128 (e.g., the “friend” is not a registered user of thecontent graph 128), then the network import manager 174 may obtaininformation regarding the “friend” from the social network 172, and mayadd a new node associated with the “friend” in the content graph 128.Content associated with the “friend” in the social network 172 (that isaccessible to the user 108) may also be added to the content graph 128.According to an example embodiment, metadata indicating the source ofthe update data may be stored in the content graph 128.

For example, the network import manager 174 may determine otherinformation that may be available via other sources (news pages on theInternet, blogs, searches on keywords of interest), and may periodicallyupdate the content/connection information stored in the content graph128.

According to an example embodiment, the question processing manager 102may be embodied via executable instructions that may be stored on acomputer-readable storage medium, as discussed below. According to anexample embodiment, the computer-readable storage medium may include anynumber of storage devices, and any number of storage media types,including distributed devices.

FIG. 2 is a block diagram of an example system for managing userquestions. For example, the system of FIG. 2 may include the receivingdevice 114 discussed above with regard to FIG. 1. As shown in FIG. 2, asystem 200 may include a question processing receiving engine 202 thatmay include a question input engine 204 that may be configured toreceive a first question 206 from a first device user 108, the firstquestion 206 associated with a request for responses to the firstquestion 206 from a group of connection users associated with the firstdevice user 108 via one or more friend connections to the first user 108in a content network. For example, the content network may include acontent network that includes the content graph 128.

For example, the first user 108 may provide an input indicating thefirst question 206 via an input device associated with the questionprocessing receiving engine 202 (e.g., a keyboard, touchpad,touchscreen, mouse click, audio input device for receiving voice input),the request input received by the question input engine 204.

According to an example embodiment, the question processing receivingengine 202 may be embodied via executable instructions stored on acomputer-readable storage medium. For example, the executableinstructions may, when executed, cause one or more data processingapparatuses to perform steps that may be associated with exampletechniques as discussed further herein.

According to an example embodiment, a user device memory 208 may beconfigured to store the first question 206. According to an exampleembodiment, a device data repository 210 may be configured topersistently store data associated with the question processingreceiving engine 202. For example, the device data repository 210 may belocated on a disk drive or other storage medium associated with thequestion processing receiving engine 202.

According to an example embodiment, a receiving user interface engine212 may manage communications between the user 108 and the questionprocessing receiving engine 202. For example, the display 116 maycommunicate with the question processing receiving engine 202, viainternal device bus communications, or via at least one networkconnection.

According to an example embodiment, the data mining machines 608 mayanalyze many different sources of information, for example, for use ininferences for helping users (e.g., requestors and their friends) reachtheir respective individual decisions regarding asking questions,answering questions, and actions to take based on their decisions.

FIGS. 7A-7C depict example user views of example graphical displays on adevice. According to an example embodiment, techniques discussed hereinmay provide a question processing system. As shown in FIG. 7, a user mayask questions and may receive responses to the questions from friends ofthe user. For example, a device 702 may correspond to the receivingdevice 114 discussed above with regard to FIGS. 1 and 2. A displayedscreen 704 may provide a user with areas for viewing information thatmay be relevant to submitting a question for transmission to friends ofthe user. For example, the first user 108 may enter a question in a textbox 706 in response to a prompt indicated as “What's on my mind?”. Asshown in FIG. 7A, the first user 108 may enter text in the text box 706,as suggestion questions are presented in a suggestion box 708 (e.g.,user suggestion questions 168 as determined by the suggestiondetermination engine 166, and transmitted to the device 702 via thesuggestion output engine 170, as discussed above).

As discussed above, when the first user 108 activates the applicationassociated with the screen of the device 702, an intent to ask aquestion may be transmitted to the question processing manager 102, andreceived by the intent receiving engine 162. The suggestiondetermination engine 166 may determine user suggestion questions 168,for example, based on information obtained from the content graph 128,from information received by the intent receiving engine 162 (e.g.,current location of device 702, time of day associated with device 702),and from other sources (e.g., season, current events, popular entities,current sales events) that may be obtained from web sources or otherlibraries of information. For example, a history of questionsasked/answered recently by the first user 108 may be provided as usersuggestion questions 168 (e.g., obtained from the content graph 128).

According to an example embodiment (not shown), the first user 108 mayalso receive prompts via audio transmission, or any other form of useroutput discernable to the first user 108. According to an exampleembodiment, the user suggestion questions 168 may be presented to thefirst user 108 via audio transmission, and the first user 108 mayprovide the question 106 via voice commands (or via any other form ofinput discernable to the first user 108 and the device 702). Thus, thedisplay 116 is not limited to a graphical display as shown in FIG. 7A,but may also include one or more devices that provide input/outputbetween the device 702 and the first user 108 (e.g., microphones andspeakers for audio input/output).

When the first user 108 has determined the question 106 as entered inthe text box 706 of FIG. 7A, the first user 108 may activate a submitbutton 710 (indicated as “Ask my friends” in FIG. 7A) to requesttransmission of the question 106 to the question processing manager 102,for transmission to friends of the first user 108.

As shown in FIG. 7B, a “Browse Questions” 712 feature may provide a list714 of questions asked by friends of the first user 108, with resultsupdated as of a time of the refresh operation by the first user 108 onthe device 702. According to an example embodiment, the first user 108may refresh a screen 712 to receive currently asked questions 106, askedby friends of the first user 108, in real time. As shown in FIG. 7B, aquestion 716 from Jake may inquire whether friends of Jake like risotto.

As shown in FIG. 7B, activation of a search button 718 may provideadditional information for helping a first user 108 to learn more aboutthe question content. For example, if the question includes a referenceto visiting “Zixxleberg”, then the question content determination engine144 may initiate mining of sources of data to determine information thatmight be helpful/relevant for users to better understand the question,before submitting a response, and may associate the information with thesearch button 718 (e.g., via the search link 136, as discussed above).For example, the question content determination engine 144 may obtaininformation associated with other questions relating to “Zixxleberg”,asked by other users, to determine a context for the term (e.g., afictional place referenced in a comic book several generations ago, or asandwich offered briefly by a local restaurant).

As shown in FIG. 7B, a “thumbs up/thumbs down” results area 720indicates current results associated with answers already received forthe risotto question (e.g., 5 down, 15 up in this example). If the firstuser 108 (e.g., a user named John) is a user selected to receive thequestion for a response, then the first user 108 may provide a response,for example, by activating an icon for “thumbs up” or “thumbs down”(e.g., yes/no response).

As shown in FIG. 7C, a “My Questions” 722 feature may provide a list ofquestions provided by the first user 108, with results 724 provided sofar by friends of the first user 108. According to an exampleembodiment, the friends submitting responses may provide the responsesanonymously, and thus the first user 108 may not know who responded.According to an example embodiment, the friends may agree to let thefirst user 108 know who provided the responses, and the first user 108may be able to view a list of responders, with respective responses, viaa click or activation of one of the results icons (e.g., up or downicon).

According to an example embodiment, the search button 718 of FIG. 7C mayprovide the first user 108 with information regarding satisfaction ofelements of the question 106. For example, if the first user 108submitted a question 106 regarding eating risotto, the question contentdetermination engine 144 may determine that a restaurant near thecurrent location of the first user 108 is associated with favorablecomments regarding their risotto (e.g., via a search engine thatprovides rankings and location information), or that a particular typeof risotto may taste better than other types, and may provide links tothe rankings, type, and location information with the search link 136.The first user 108 may then access the information via one click of thesearch button 718 of FIG. 7C, to make informed, quick decisions.

FIG. 8 depicts an example content graph. As shown in FIG. 8, a contentgraph 800 may include user nodes 802, 804, 806, and 808 associated withusers John, Anna, Nicole, and Jake, respectively. As shown in FIG. 8,the user nodes 804, 806, and 808 are connected to the user node 802 viaedges 810, 812, 814, respectively, indicating “Friend” relationshipswith the user node 802. Thus, the content graph 800 indicates that usersAnna, Nicole, and Jake are friends with John (e.g., connection users(Anna, Nicole, and Jake) having a connection user association with thefirst user 108 (John) in the content graph 128, as discussed above).

As shown in FIG. 8, a question node 816 represents a question regarding“risotto” (e.g., the question “Should I eat risotto?” as shown in FIG.7c ). As shown in FIG. 8, the user node 802 is connected to the questionnode 816 via an edge 818, indicating an “Asked” relationship with thequestion node 816. As shown in FIG. 8, the user nodes 808 and 804 areconnected to the question node 816 via edges 820 and 822, respectively,indicating “Answered” relationships with the question node 816.

Thus, the content graph 800 of FIG. 8 indicates that John asked aquestion regarding risotto, and that John's friends Jake and Annaprovided responses to the risotto question.

According to an example embodiment, the responses to questions may bestored in the content graph 800, for example, as separate response nodesrelated to the respective question, the respective responder/user node,and to the originator/user node of the question, or the responses may bestored with the question nodes and/or the respective responder/usernodes. Cumulative results may be stored in association with respectivequestion nodes. Thus, according to an example embodiment, auser/responder may be able to change his/her response after initialsubmission.

According to an example embodiment, attributes associated with nodes maybe stored in association with the nodes (e.g., as lists, linked lists,hash tables). For example, histories and demographic informationassociated with individual users may be stored in association with theuser nodes.

The content graph 800 of FIG. 8 is shown as including a question node,four user nodes, and edges representing friend relationships andrelationships of asking and answering a question; however, the contentgraphs 128 and 800 may include a very large number of nodes and edges,and may support a very large number of node types and edge types.

Example techniques discussed herein may thus provide systems for quickand efficient question and answer/opinion interplay between friends in amobile setting. For example, questions and results may be served inreal-time to clients through a web service. If clients are not currentlyavailable online, questions may be pushed to candidate responders viainstant messages, email, phone call, or any other communication meansspecified by each respective user.

Customer privacy and confidentiality have been ongoing considerations inonline environments for many years. Thus, a service for processingquestions may provide user information regarding risks associated withthe user providing personal information, for example, for use inassociation with a user profile. An example service for processingquestions may offer options for a potential user to use the service onindividual one-time sessions in lieu of a subscription in which the userinformation may be persistently stored for retrieval upon subsequentrequests for information regarding questions related to their friends.

A service for processing questions may also request permission frompotential users before sharing user information with sponsors such ascompanies providing advertising or coupons. An example service forprocessing questions may inform a potential user that he/she may receivea list of relevant questions/results, and that the user may decline toprovide personal information other than an online address (i.e., as atarget for transmitting the questions/results) and any other optionalinformation that the user may elect to provide (e.g., a gender, an agerange, an income range, an ethnicity, personal preferences permission),for use in updating/upgrading logic for processing questions for allusers of the service. For example, a prospective user may wish to view ademo of the service, and may receive lists that have been approved fordissemination to users external to a group of connected friends.

An example service for processing questions may request an email addressfor sending an email to confirm permission before user personalinformation is entered into the system, to ensure that the user isinformed of potential risks of electronically stored personal/privateinformation. Further, authentication techniques may be included in orderfor the user to continue to use the service for processing questions.For example, a user identifier and password may be requested for futureaccess to the system. As another example, an authorized fingerprint oraudio identification (e.g., via voice recognition) may be requested forthe access. Additionally, access to networked elements of the system maybe provided via secured connections (or hardwired connections), andfirewalls may be provided to minimize risk of potential hacking into thesystem.

Implementations of the various techniques described herein may beimplemented in digital electronic circuitry, or in computer hardware,firmware, software, or in combinations of them. Implementations mayimplemented in a propagated signal, or, alternatively, as a computerprogram product, i.e., a computer program tangibly embodied in aninformation carrier, e.g., in a machine usable or machine readablestorage device (e.g., a magnetic or digital medium such as a UniversalSerial Bus (USB) storage device, a tape, hard disk drive, compact disk,digital video disk (DVD), etc.), for execution by, or to control theoperation of, data processing apparatus, e.g., a programmable processor,a computer, or multiple computers. A computer program, such as thecomputer program(s) described above, can be written in any form ofprogramming language, including compiled or interpreted languages, andcan be deployed in any form, including as a stand-alone program or as amodule, component, subroutine, or other unit suitable for use in acomputing environment. A computer program that might implement thetechniques discussed above may be deployed to be executed on onecomputer or on multiple computers at one site or distributed acrossmultiple sites and interconnected by a communication network.

Method steps may be performed by one or more programmable processorsexecuting a computer program to perform functions by operating on inputdata and generating output. The one or more programmable processors mayexecute instructions in parallel, and/or may be arranged in adistributed configuration for distributed processing. Method steps alsomay be performed by, and an apparatus may be implemented as, specialpurpose logic circuitry, e.g., an FPGA (field programmable gate array)or an ASIC (application specific integrated circuit).

Processors suitable for the execution of a computer program include, byway of example, both general and special purpose microprocessors, andany one or more processors of any kind of digital computer. Generally, aprocessor will receive instructions and data from a read only memory ora random access memory or both. Elements of a computer may include atleast one processor for executing instructions and one or more memorydevices for storing instructions and data. Generally, a computer alsomay include, or be operatively coupled to receive data from or transferdata to, or both, one or more mass storage devices for storing data,e.g., magnetic, magneto optical disks, or optical disks. Informationcarriers suitable for embodying computer program instructions and datainclude all forms of non volatile memory, including by way of examplesemiconductor memory devices, e.g., EPROM, EEPROM, and flash memorydevices; magnetic disks, e.g., internal hard disks or removable disks;magneto optical disks; and CD ROM and DVD-ROM disks. The processor andthe memory may be supplemented by, or incorporated in special purposelogic circuitry.

To provide for interaction with a user, implementations may beimplemented on a computer having a display device, e.g., a cathode raytube (CRT) or liquid crystal display (LCD) monitor, for displayinginformation to the user and a keyboard and a pointing device, e.g., amouse or a trackball, by which the user can provide input to thecomputer. Other kinds of devices can be used to provide for interactionwith a user as well; for example, feedback provided to the user can beany form of sensory feedback, e.g., visual feedback, auditory feedback,or tactile feedback; and input from the user can be received in anyform, including acoustic, speech, or tactile input.

Implementations may be implemented in a computing system that includes aback end component, e.g., as a data server, or that includes amiddleware component, e.g., an application server, or that includes afront end component, e.g., a client computer having a graphical userinterface or a Web browser through which a user can interact with animplementation, or any combination of such back end, middleware, orfront end components. Components may be interconnected by any form ormedium of digital data communication, e.g., a communication network.Examples of communication networks include a local area network (LAN)and a wide area network (WAN), e.g., the Internet.
